Other energy brands A-M

Looking for a green tariff, a cheaper tariff or a more personal service? Here, we tell you what you need to know about the smaller energy suppliers, listed alphabetically from A-M.

There are currently more than 60 firms you can buy your gas and electricity from in England, Scotland and Wales. That’s more than 11 times the number that existed in the 1990s when the market was privatised, creating the six biggest suppliers: British Gas, EDF Energy, Eon, Npower, Scottish Power and SSE.

Although these six still dominate the market (along with Ovo Energy which recently bought SSE’s customers) there are lots of small energy companies trying to set themselves apart. So use this to your advantage and seek out an energy supplier that suits you.

To help you get started, here's an introduction to every small energy supplier in Great Britain. Click on a company’s name below to skip to its profile.
